A Wash. Skydiver vanished on Thursday and he jumped from the aircraft but failed to show at near the landing zone by Mount Si in Seattle. Researchers resumed the search for the unnamed 29-year-old on Friday, hoping that he was simply stuck in a tree or hunkered down for the night.

The pilot of the helicopter the missing skydiver jumped from reported that the man failed to show at the landing zone at 2:30 p.m. on Thursday. The Kings County sheriff's office said the man, who was in a winged flight suit, could have travelled a great distance in a short period of time. It is unknown, however, if the missing skydiver's parachute ever opened.

The search began on Thursday, and encompassed a five-square-mile area. However, the search was called off due to darkness on Thursday night, but resumed Friday morning. The sheriff's office estimates that 40-50 people are on the search team, according to MSNBC.

"With the daylight hours, we'll also have the opportunity to go off the trail more and maybe do some technical rope descents into some areas where he might have ended up," Sgt. Cindi West, of the King County Sheriff's Office, told KIRO-TV.

The pilot of the helicopter said three men were alternating going up in the helicopter to jump at 6,500 feet, with one jumping while the others waited. The county's helicopters were unable to help search for the skydiver because of heavy fog.
